Re: Repairing YM-3591AAR power supply (HP P/N 81-00000051)

I have not looked here for a long time. I replaced the resistor R149 with 3.65 k. Now, by adjusting the tuning resistor VR101 - I got 14.04 volts at the output of the power supply. Protection circuits and error compensation work within the factory settings. But I need 15-16 volts at the output. I am looking for a solution, but have not yet found it. Here are some circuit diagrams. Surely there are a lot of mistakes. But this gives at least some idea (global) of the regulation and feedbacks. My goal was to increase the tension. Therefore, I paid little attention to drawing nodes that I did not need.
